Abstract: Aspects of the subject application may include, for example, identifying FOV and OOS tiles of the video content. The FOV and OOS tiles are received from a video server. The FOV and OOS tiles are encoded using AVC and a first layer of SVC, respectively. Further embodiments include providing the FOV and OOS tiles for presentation on a display, detecting a change in a field of vision, and identifying other FOV tiles of the video content, which comprise a portion of the OOS tiles. Also, embodiments include requesting the portion of the OOS tiles and receiving the portion of the OOS tiles from the video server over the communication network, which are encoded using an enhancement layer of SVC and then provided, to the display, according the enhancement layer in conjunction with the providing of the OOS tiles according to the first layer.

Abstract: Aspects of the subject disclosure may include, for example, system for tile-based video streaming using a proxy executing at a mobile edge cloud, which adaptively offloads decoding and merging of video tiles from mobile devices to the mobile edge cloud. A processing system including the proxy communicates with a video server and a client device. The proxy receives a request for video content from a client device; the request includes historical field of view (FoV) information. The proxy predicts a client FoV, requests video tiles from the server, downloads the tiles from the server, generates a video chunk by decoding and merging the downloaded tiles, and delivers the video chunk to the client device. The client device performs local decoding and rendering of the generated video chunk. Other embodiments are disclosed.

Abstract: Systems and methods for providing accurate data about the distribution of UEs after disaster include a movable eNodeB that is moved to at least three locations. The coordinates for the at least three locations are determined and the distance between the eNodeB and a plurality of UEs is measured. The location of each UE relative to the eNodeB is calculated based on the distance between the eNodeB and the plurality of UEs using trilateration. The coordinates for the UEs is then calculated based on the coordinates for the at least three locations and the determined location of the UEs relative to the eNodeB.
